I don't think that's a comprehensive list, e.g. https://en.wikipedia.org/wiki/Tyrannosaurus#Resurgent_intere... mentions that 42 skeletons have been found in western North America. I don't have the page number, but I also remember reading in Steve Brusatte's "The Rise and Fall of Dinosaurs" that there are some areas where T. rex's were so common that you can find teeth relatively easily.

Agreed that findings this well preserved are incredibly rare and fortunate.
